Assessing an SEO company’s technical skills requires evaluating 15-20 different competencies through practical tests, portfolio reviews, and detailed questioning. Technical expertise separates capable agencies from those relying on basic tactics. Understanding assessment methods helps identify agencies with genuine technical depth versus surface-level knowledge.

Technical audit samples provide the best evidence of analytical capabilities and problem-solving skills. Request example audits from previous clients (with permission) showing how they identify and prioritize issues. Look for comprehensive analysis covering crawlability, indexation, site architecture, and page speed. Quality audits demonstrate systematic thinking and technical understanding beyond automated tool reports.

Live website analysis during sales calls reveals real-time technical competency. Ask agencies to review your site while screen-sharing, explaining what they observe. Competent technicians quickly identify obvious issues, explain implications, and suggest solutions. Watch for reliance on single tools versus comprehensive understanding.

Certification verification provides baseline competency indicators, though experience matters more. Google Analytics, Google Ads, and platform-specific certifications show foundational knowledge. However, certifications don’t guarantee practical application skills. Advanced agencies often have team members with multiple certifications plus years of implementation experience.

Tool proficiency questioning reveals whether agencies use industry-standard platforms effectively. Ask which tools they use for crawling, log file analysis, and performance monitoring. Competent agencies use multiple tools including Screaming Frog, Google Search Console, and specialized platforms. They should explain why they choose specific tools for different tasks.

Technical assessment areas include:
• JavaScript SEO understanding and rendering issues
• International SEO with hreflang implementation
• Site migration experience and methodology
• Schema markup complexity and types
• Core Web Vitals optimization strategies
• Log file analysis capabilities

Problem-solving scenarios test practical application of technical knowledge. Present hypothetical situations like “traffic dropped 50% overnight” or “new pages aren’t getting indexed.” Evaluate their diagnostic approach, not just solutions. Strong agencies follow systematic troubleshooting processes rather than guessing.

Code literacy evaluation determines whether agencies can work with developers effectively. While SEO companies needn’t be programmers, they should understand HTML, CSS basics, and JavaScript implications. Ask about their experience with different CMS platforms and custom builds. Technical communication abilities matter as much as raw knowledge.

Case study deep dives reveal technical problem-solving in real situations. Request detailed explanations of technical challenges they’ve solved. How did they diagnose issues? What tools did they use? How did they implement solutions? Specific examples demonstrate practical experience beyond theoretical knowledge.

Team technical depth assessment goes beyond sales representatives to actual implementers. Ask about technical team members’ backgrounds, specializations, and experience levels. Request to speak with technical leads during evaluation. Agencies hiding technical staff might outsource or lack genuine expertise.

Testing methodology through small paid projects provides definitive capability proof. Hire agencies for technical audits before committing to full engagements. Evaluate their audit quality, recommendations, and communication. This investment of $1,000-2,500 prevents costly mistakes from choosing technically weak agencies.

Identifying ethical SEO companies requires evaluating 10-15 different indicators from tactics to transparency. Approximately 25-30% of agencies use questionable methods risking penalties. Understanding ethical markers helps avoid agencies that could damage your site’s long-term viability.

Google Webmaster Guidelines compliance forms the foundation of ethical SEO. Agencies should explicitly follow Google’s quality guidelines without attempting manipulation. They avoid cloaking, hidden text, and deceptive redirects. Guideline adherence prevents penalties and maintains sustainable rankings.

Link building transparency reveals ethical standards immediately. Ethical agencies explain link sources, avoid paid links, and reject private blog networks. They pursue editorial links through value creation. Agencies hiding link sources or guaranteeing quantities likely use unethical tactics.

Content originality standards separate ethical agencies from those cutting corners. They create unique, valuable content rather than spinning or copying. Plagiarism checking and proper attribution demonstrate integrity. Original content builds genuine authority.

Reporting honesty shows whether agencies acknowledge failures and challenges. Ethical agencies admit when strategies don’t work and explain setbacks. They don’t hide problems or manipulate data. Transparent reporting builds trust despite temporary disappointments.

Ethical indicators include:
• Clear contract terms and pricing
• Realistic timeline expectations
• White-hat tactics exclusively
• Client reference availability
• Industry reputation and reviews
• Professional association memberships

Competitive tactics reveal ethical boundaries. Ethical agencies don’t engage in negative SEO against competitors. They avoid false reviews or malicious attacks. Competition through superior optimization demonstrates confidence and integrity.

Client ownership rights indicate ethical business practices. Agencies should acknowledge client ownership of content, accounts, and data. They provide passwords and transfer assets upon request. Holding assets hostage violates ethical standards.

Communication practices demonstrate respect and professionalism. Ethical agencies respond promptly, explain clearly, and maintain confidentiality. They don’t use high-pressure sales tactics or make unrealistic promises. Professional communication indicates ethical operations.

Long-term focus versus quick wins shows strategic integrity. Ethical agencies prioritize sustainable growth over temporary gains. They resist client pressure for risky tactics. Sustainable strategies protect long-term success.

Industry reputation through reviews, references, and peer recognition provides external validation. Check Better Business Bureau ratings, online reviews, and industry forums. Ask for references and actually contact them. Ethical agencies welcome scrutiny while unethical ones deflect investigation. Reputation accumulates over years of ethical practice.

Modern SEO companies must track mobile performance separately, as mobile comprises 60-70% of searches with significantly different behavior patterns. Mobile tracking costs an additional $200-500 monthly for tools and analysis. Understanding mobile capabilities helps evaluate whether agencies recognize mobile-first reality.

Mobile ranking tracking reveals different positions than desktop for many keywords. Agencies monitor both device types separately since Google uses mobile-first indexing. They identify mobile-specific opportunities and problems. Separate tracking uncovers optimization priorities invisible in combined data.

Mobile user behavior metrics show different engagement patterns than desktop. Mobile sessions are shorter but more frequent. Conversion paths differ significantly. Agencies analyze mobile-specific funnels and friction points. Understanding mobile behavior enables targeted optimization.

Page speed monitoring for mobile devices requires special attention. Mobile Core Web Vitals often fail despite passing desktop scores. Agencies track mobile-specific metrics like 3G/4G performance. They optimize for slower connections and smaller screens. Mobile speed directly impacts both rankings and conversions.

Local mobile tracking captures “near me” searches and map interactions. Mobile drives most local searches with immediate intent. Agencies monitor mobile local pack visibility and click-to-call rates. Local businesses especially need mobile-specific optimization.

Mobile tracking capabilities include:
• Device-specific rankings monitoring
• Mobile conversion funnels
• App indexation and deep linking
• AMP performance if applicable
• Voice search optimization
• Mobile SERP features

Mobile-specific technical issues require dedicated monitoring. Agencies check mobile usability errors, viewport configuration, and touch target sizing. They identify interstitial penalties and mobile-first indexing issues. Technical monitoring prevents mobile-specific problems.

Cross-device tracking reveals how users move between mobile and desktop. Many users research on mobile but convert on desktop. Agencies implement user ID tracking and attribution modeling. Understanding cross-device journeys prevents undervaluing mobile’s contribution.

Mobile commerce tracking for e-commerce sites shows different patterns than desktop. Mobile cart abandonment rates exceed desktop significantly. Agencies track mobile checkout friction and payment issues. M-commerce optimization requires specific attention.

International mobile considerations include device diversity and connection speeds. Agencies track performance across different devices and networks. They optimize for regional mobile behavior differences. Global campaigns need location-specific mobile strategies.

Reporting separation ensures mobile performance receives appropriate attention. Combined reports hide mobile issues in averaged data. Agencies should provide distinct mobile sections in reports. Clear separation drives mobile-specific improvements. Mobile-first thinking requires mobile-first measurement and optimization.
